Lines that are neither parallel nor perpendicular.
If lines neither intersect nor are parallel, then they must be drawn in 3D space, or a higher dimension.(These lines are called skew lines)
Perpendicular lines intersect at a 90 degree angle. Parallel lines do not intersect, nor would they ever intersect if continued infinitely.
No. Normally, two lines will uniquely identify a plane, unless they happen to be parallel. If you add a third line, it will usually not be in the same plane.* * * * *Not quite. Two lines that meet will uniquely identify a plane. But you can have lines that are neither coplanar nor parallel.For example, consider a cube and think of the line defined by the front bottom and one of the back verticals. Neither parallel, nor coplanar.
Are very common but do not have any particular name. Sit in the corner of a cuboid room. Consider one line which is defined by the floor and the wall on your left. Consider the other as that formed by the ceiling and the wall on your right.
No, oblique lines are neither parallel nor perpendicular
Lines that are neither parallel nor perpendicular.
Lines that are neither parallel nor perpendicular.
Neither perpendicular nor parallel
You may have neglected to copy something else that goes with the question, as there are no "above lines".

The straight line equation is y = mx + b. If they do not cross and have the same slope they are parallel; if they cross and the slope (m) of one of them is the negative inverse slope of the other (-1/m) they are perpendicular. Otherwise they are neither
Skew Lines. :)
parallel
If the second equation is: y minus 2x equals 3, then:y - 2x = 3 ⇒ y = 2x + 3 and it is parallel to y = 2x.Otherwise (with with missing operator as "plus", "multiply" or "divide"), the lines are neither parallel nor perpendicular.
Points cannot be parallel or perpendicular. So they never are.
